Dephasing and breakdown of adiabaticity in the splitting of Bose Einstein Condensates
L. Pezze, A. Smerzi, G. P. Berman +2
We study the quantum dynamics of a BEC condensate trapped in a double-well potential with a rising interwell barrier. We analytically find the characteristic time scales of the spl…
Variational Approach to the Modulational Instability
Z. Rapti, P. G. Kevrekidis, A. Smerzi +1
We study the modulational stability of the nonlinear Schrödinger equation (NLS) using a time-dependent variational approach. Within this framework, we derive ordinary differential…
Propagation of sound in a Bose Einstein condensate in an optical lattice
C. Menotti, M. Kramer, A. Smerzi +2
We study the propagation of sound waves in a Bose-Einstein condensate trapped in a one-dimensional optical lattice. We find that the velocity of propagation of sound wavepackets de…
Double-Slit Interferometry with a Bose-Einstein Condensate
L. A. Collins, L. Pezze', A. Smerzi +2
A Bose-Einstein "double-slit" interferometer has been recently realized experimentally by (Y. Shin et. al., Phys. Rev. Lett. 92 50405 (2004)). We analyze the interferometric steps…
Observable Signature of the Berezinskii-Kosterlitz-Thouless Transition in a Planar Lattice of Bose-Einstein Condensates
A. Trombettoni, A. Smerzi, P. Sodano
We investigate the possibility that Bose-Einstein condensates (BECs), loaded on a 2D optical lattice, undergo - at finite temperature - a Berezinskii-Kosterlitz-Thouless (BKT) tran…
Efficient and robust initialization of a qubit register with fermionic atoms
Luciano Viverit, Chiara Menotti, Tommaso Calarco +1
We show that fermionic atoms have crucial advantages over bosonic atoms in terms of loading in optical lattices for use as a possible quantum computation device. After analyzing th…
